Turnigy 9x - Throttle control doesn't seem to function? am I doing something wrong? - Discussions

So my friend and I have been working on getting our hexacopter up and running and are now doing initial setup of the APM 2.5 and receiver. We are having some issues getting the throttle control to register at all when calibrating in the mission planner. Maybe we are missing some obvious step that hopefully someone can help out with?

We are running a stock Turnigy 9x set in mode2 connected to APM 2.5

We are relatively inexperienced when it comes to RC receivers and all of the options in them, but we tried to keep everything as default as we could have. I'm starting to wonder if it might be a hardware problem just because pitch/yaw/roll are all working just fine?

Also, hopefully it's not a dumb question, but we haven't connected our ESC's yet and only wanted to see that the settings were right in the mission planner first. Transmitter->APM->PC. Will that work for initial testing or do we need to have it all connected to the other hardware (ESC/motors/etc) before we start the calibration?

Thanks in advance!

Might be an issue with the throttle trim setting on your Tx, but it also might be hardware. Or if you have "throttle hold" enabled on the Tx maybe it's switched on. Or does the Turnigy Tx and/or Rx have some sort of throttle arming feature?

I'm a fan of Turnigy gear for certain applications but personally I wouldn't be at all comfortable using their Rx or Tx on anything as critical as a hex or big quad. At the least I would wring it out thoroughly on something cheap and safe, like a park-class airplane, before committing a hex to it. There's a lot of overpriced/overkill stuff on the shelves of the RC world but there's also a lot of cheap stuff that can issue nasty surprises.

On APM2 and I presume on 2.5 you don't need to power the ESC/Motors to dial everything in (except motor rotation direction), rather you can power the APM and Rx via a standalone BEC or via USB, If you do hook up the motors on the bench be sure to remove the props first. Nothing will ruin your day faster than a hex doing an unscheduled flip in your living room...

Thanks for the quick replies!

We ran the diagnostics on the Turnigy and it looks like the throttle control is just outputting noise and does not respond to any input. We are guessing that the POT came to us broken (apparently a somewhat common thing?). We are gonna crack the case open and attempt to clean or repair. If that fails, we may look at replacing with some of the Aurora 9 Gimbals that sound much more reliable.

I'm with you that we don't want to have have unreliable equipment piloting expensive stuff!
